Hydraulic Oil Care for the ME-Hydraulic, 2-Stroke Diesel Engines | Container Vessels
Customer Case
System: Marine Diesel Engines
Hydraulic control of the injection pump and exhaust valves of the main engines (ME-Hydraulic).
Diesel engine, 2-stroke: MAN 12K98 ME-C6
Oil type: Lubricating oil, Mobilgard 300
Viscosity: 111 cSt at 40°C
Oil volume: 16,000 liters
Container vessel
Marine engine, 2-stroke, type MAN 12K98 ME-C6
Solution
Installation of a CJC® Hydraulic Filter 427/81 with CJC® Fine Filter Insert B 427/81 (3 µm absolute) for continuous fine filtration and dewatering of the hydraulic oil (24/7).
Dirt holding capacity: up to 144 kg
Water absorption capacity: approx. 14.4 l
Filtration degree: 3 µm absolute, retention rate < 1 µm
Filter material: 100% natural fibres
The CJC® Hydraulic Filter removes particles, water, oil ageing products and acidic components from the oil with high efficiency.

Savings & Benefits for our Customer
The installation of the CJC® Hydraulic Filter has ecological and economical advantages for our customer.
Due to the convincing results on the first container vessel, Hapag-Lloyd decided to install a CJC® Hydraulic Filter on further 24 vessels of different classes, extending the advantages of the CJC® Hydraulic Filter to other container vessels and optimizing a further part of the fleet.
- Prevention of malfunctions and failures in the ME hydraulic system ensures more reliable engine operation.
- Since the installation of the CJC® Hydraulic Filter, no more unplanned breakdowns occured.
- Longer service life of oil-lubricated hydraulic components reduces the need for repairs and spare parts.
- Cost reduction due to proactive maintenance, as expensive emergency repairs are minimized.
- Increased operational reliability and efficiency of the hydraulic system leads to more stable engine performance.
- Oil change of 16,000 liters of hydraulic oil avoided, thus reducing CO2 emissions.
- 76,800 kg of CO2 are saved per avoided oil change *)
*) per 1 Litre of oil approx. 4.8 kg CO2 (production/disposal)
